The invention relates to a motor vehicle seat with an underframe, onto which a back rest is linked in a swiveling manner on one hand and which carries on the other hand a bucket seat, which is embodied in a plane manner, and which is connected to the underframe on one hand in its front area via a swiveling axis running crosswise and which is connected on the other hand in its back area via elastic, which effect a spring suspension of the bucket seat around the swiveling axis. For adjusting the seat depth of the motor vehicle seat i) the swiveling axis is kept in the longitudinal guide in an adjustable manner, the course thereof is essentially parallel to the level of the bucket seat and crosswise to the swiveling axis, whereby an adjustment device for the fixation of the swiveling axis is provided in the longitudinal guide and ii) the elastic is attached to the bucket seat as well as to the underframe of the carriage in a flexible manner.

The invention relates to a motor vehicle seat with a back rest and a seat which is supported by an adjustable underframe, which itself is supported via seat carriers of a longitudinal adjustment device. The back rest is supported by a back rest support, which is connected with the back rest via a back rest mounting. The back rest support is joined in a hinge with the seat carriers via front and back brackets of the back rest support and the seat is joined in a hinge with the seat carriers via front and back brackets of the seat support in an adjustable way.

A locking device for a longitudinal-adjustment device of a vehicle seat. The longitudinal-adjustment device includes two pairs of rails, each of which being releasably lockable by a catch and consisting of a floor rail and a seat rail. The seat rails being connected to a seat support through a height-adjustment device. An activation lever of the locking device is laterally hinged to the seat support and serves to activate the catch. This activation lever is hinge-connected to a transmission link which in turn is hinged to the seat rail and has a locking area which includes the catch or activates a separate catch.
摘要:
A process for separating higher hydrocarbons from a gas mixture containing the latter and lower-boiling components by rectificatory decomposition is described. The feed gas mixture (6) is partially condensed (7) and fed to a separation column (9). A bottom fraction (27), rich in higher hydrocarbons, is removed from the bottom of the separation column (9), and a top fraction (10), rich in lower-boiling components, is removed from the top of the separation column. The top fraction (10) is partially condensed (11) and the resultant condensate is used as reflux for the separation column (9).Both the partial condensation of the feed gas mixture and the partial condensation of the top fraction are produced by indirect heat exchange (7, 11) with a refrigerant, which consists of several components and is conveyed in an external circuit (18).
摘要:
A compressor unit that has a compressor component and a condensate filter that is used to precipitate water and oil condensed from a compressed gas stream. For the environmentally friendly disposal of the condensate, a filter device containing a filter material is arranged so that a warm air stream entering the filter device after passing through the condensate filter condenses the water in the filtrate stream. The condensate is soaked up in the filter device by the filter material and, with the help of the air stream, which can be the warmed outgoing air of a cooling device of the compressor component, the water contained in the condensate is evaporated, while the oil-containing components of the condensate are adsorbed in the filter material for subsequent disposal. The filter material is preferably placed in the filter device in the form of filter elements arranged preferably in several rows behind one another at predetermined distances in the direction in which air flows through. The filter element can be designed as an osmotic filter cloth which is formed as tubes or it can be made of spiral-shaped, wound sheets of such filter material. Suitably, the filter device with the filter material contained in it is designed as a replaceable, disposable device, for example in the form of a module.
摘要:
In a process for the separation of hydrocarbons from a hydrocarbon mixture which optionally contains components boiling lower than methane, the crude gas stream is partially condensed and separated into a gaseous fraction and a liquid fraction. The liquid fraction is introduced into a rectification column wherein further separation is performed. The residual gas obtained at the head of the rectification column is partially condensed and introduced into a scrubbing column wherein the condensed portion of the residual gas is used as a scrubbing medium to scrub out low-boiling components from the separated, gaseous fraction. For covering the refrigeration requirement of this process, a portion of the residual gas from the rectification column, prior to being fed into the scrubbing column, is branched off and expanded for production of refrigeration. After heat exchange with process streams to be cooled, this portion of the residual gas stream is readmixed to the residual gas stream of the rectification column.
摘要:
A process for the separation of C.sub.2+ hydrocarbons from natural gas under pressure wherein the natural gas is cooled (2, 6), partially condensed, and separated (9) into a liquid fraction and a gaseous fraction. The liquid fraction (10) is subcooled (11) and then expanded into the upper zone of a rectifying column (7). The gaseous fraction (23), after engine expansion (25), is also introduced into the rectifying column (7). During rectification, a product stream (37) containing essentially C.sub.2+ hydrocarbons and a residual gas stream (22) containing predominantly lower-boiling components are obtained. The residual gas stream (22) is initially heated by heat exchange (11) with the liquid fraction (10) and then heated by heat exchange (21) with the gaseous fraction obtained after partial condensation. The residual gas stream is then further heated (6, 2) by heat exchange with the feed stream of natural gas to be partially condensed. The heated residual gas is then engine expanded (28) and reheated again by heat exchange with the feed stream of natural gas to be partially condensed (2).
